description The present work deals with a new population of Artemia in the Mexican Republic, located in an ecosystem of athalassohaline waters, rich in sulphate, magnesium and sodium ions. The zone of Cuatro Ciénegas in the state of Coahuila has been widely studied; however, studies on the populations of Artemia in this zone are scarce. Artemia cysts were collected from the rustic reservoirs of the Casa Blanca saltworks. The studies of the biometry of cysts, nauplii and adults and the hatch quality of the cysts were carried out under laboratory conditions. The results obtained were compared with data of other populations of interior waters and with the population of San Francisco Bay, California, USA, that has been used as referente of the Artemia franciscana species. The cysts of Cuatro Cienegas are the smallest of the varieties of Artemia of interior waters in Mexico described to date. The measurements of the hydrated cysts (230.8 ± 20.54 µm), the decapsulated cysts (221.0 ± 33.56 µm) and the nauplii (479.71 ± 54.54 µm) show that they belong in the range established for the A. franciscana species (237 ± 14.60 µm; 212.1 ± 11.30 µm and 431 ± 23.7 µm, respectively). The size of the adults of the Coahuila population is small; the females are larger than the males (6.94 ± 1.19 mm and 6.35 ± 0.47 mm) and, though these sizes are bigger than the ones established for the A. franciscana species (10.25 ± 0.89 mm and 7.08 ± 0.37 mm), one must consider that the environment influences the size of the adults. The biological information presented here may be of help in the use of this resource in the nourishment of cultivated aquatic species.

En el presente trabajo se da a conocer una nueva población de Artemia en la República Mexicana, localizada en un ecosistema de aguas atalasohalinas, ricas en iones de sulfato, magnesio y sodio. La zona de Cuatro Ciénegas en el estado de Coahuila ha sido estudiada ampliamente; sin embargo, son escasos los trabajos sobre las poblaciones de Artemia de la zona. La recolección de los quistes de Artemia se realizo en los estanques rústicos de la salina Casa Blanca. Los estudios de biometría de los quistes, nauplios y adultos y la calidad de eclosión de los quistes se llevaron a cabo en condiciones de laboratorio. Los resultados obtenidos se compararon con los datos de otras poblaciones de aguas interiores y con la población de la Bahía de San Francisco, California, EUA, que fue considerada como referencia de la especie Artemia franciscana. Los quistes de Cuatro Ciénegas son los más pequeños de las variedades de Artemia de aguas interiores en México hasta ahora descritos. Las medidas de los quistes hidratados (230.8 ± 20.54 µm) y descapsulados (221.0 ± 33.56 µm) y de los nauplios (479.71± 54.54 µm) muestran que pertenecen al intervalo establecido para la especie A. franciscana (237 ± 14.60 µm, 212. ± 11.30 µm y 431 ±. 23.7 µm, respectivamente). La talla que alcanza el adulto de la población de Coahuila es pequeña; las hembras son más grandes que los machos (6.94 ± 1.19 mm y 6.35 ± 0.47 mm) y, aunque esta talla se sale de la establecida para la especie A. franciscana (10.25 ± 0.89 mm y 7.08 ± 0.37 mm), hay que considerar que el medio ambiente influye en el tamaño de los adultos. La información biológica que aquí se presenta sirve para aprovechar este recurso en la alimentación de especies acuáticas cultivadas.
